The roots of Audemars Piguet date back to 1875, when the 23-year-old Jules-Louis Audemars met Edward-Auguste Piguet, then only 21, at Vallée de Joux, which is considered[who?] to be the cradle of prestige watch-making. Their hometown was Le Brassus. When they graduated school they went to Vallée de Joux to start working in their favorite field of watch manufacturing. Thus Audemars started producing component parts for movements and Piguet got the job of a repasseur, whose job it was to make the final regulation of the timepiece. They founded a firm later known as Audemars, Piguet et Cie. Today the company, along with Patek Philippe and Vacheron Constantin, is sometimes claimed to be one of the top three Swiss watchmaker. Every timepiece manufactured in-house is still made using the old-fashioned hand-made technique
